Hello all,
I am Thomson from USA,The world around us is made of materials of all kind. In future, the role of materials in the human society will undergo more drastic changes. In fact, this change has already started. Understanding how materials work, what gives materials the properties that they have and how wonderful, new materials can be synthesized will form one of the major focuses of science and engineering in the coming years.

The units of resistivity don't come out right.

10^-8 Ohm * m
or
m Ohm * cm

the 'm' should be a 'mu', but unfortunately they both look the same in the latin alphabet.

Well we have permnaganate of a known conc. and back titrate it with tellurium dioxide to find out the purity of TeO2 and ... I have no idea what the reaction is ....

TeO2 + KMnO4 --->....?

Any help would be appreciated, I will be able to carry out my % nitric acid and TeO2 purity once I know the reaction products...

Thank you!
